Patent CA-2279806-A1 (CA)
Title: Non-linear optical silica thin film manufacturing method and non-linear optical silica element
Inventor: KOMEDA OSAMU
IPC: G02F1/355
Filed: 1999-08-09
Abstract: A non-linear optical silica thin film whose main material is SiO2-GeO2 is formed by irradiating with positive or negative polar particles such that polarization orientation is carried out in the silica thin film. A silica thin film is deposited on a substrate. At stages during deposition the silica thin film is irradiated with positive particles, neutral particles or non-irradiation of particles, and negative particles, thereby forming a plurality of regions having different states of polarization orientation that are in a direction of film thickness of the silica thin film. Thus, without carrying out a post process of polarization orientation, such as an application of voltage, a polarization orientation process is completed with formation of the silica thin film.

Title: Control panel assembly of a microwave oven
Inventor: JEON SEI-ILL
IPC: H05B6/68
Filed: 2000-02-18
Abstract: A control panel assembly of a microwave oven which is easy to use, including:  a front panel section having first and second cooking mode single-functional buttons comprised of a plurality of single-functional buttons for first and second cooking modes of the microwave oven, and a slot formed on the middle portion of the front panel section between the first and second cooking mode single-functional buttons; a movable switch disposed on the front panel section which is moved laterally along the slot of the front panel section; and a mode shifting switch for shifting cooking modes to the first and second cooking modes by the movement of the movable switch, wherein the first and second cooking modes are automatically selected by the movement of the movable switch, and the cooking mode single-functional button of the selected mode is exposed outward for pressing by a user. Accordingly, by simply moving the movable switch in a lateral direction, the cooking modes of the microwave oven are automatically selected. Also, the cooking mode single-functional button of the selected cooking mode is exposed, while the single-functional buttons of the unselected cooking mode are blocked by the movable switch. Accordingly, since there is a reduced number of exposed functional buttons, the appearance of the microwave oven is simple and clean. Further, by using the single-functional button for frequently cooked foods, the use of the control panel assembly becomes much easier.
Patent CA-2299943-A1 (CA)
Inventor: ROGERS SHANE M
IPC: H04L12/64
Filed: 2000-03-03
Abstract: A packet network interface for delivering streaming data to an analog output is described which can compensate for a sampling rate mismatch between the far-end transmitter and the local receiver by monitoring the rate of reception of packets and adjusting the local (receive) sampling rate respective to said rate of reception.   Typically, the rate of reception of packets is monitored by monitoring the level of a jitter buffer used to compensate for variable delays in the rate of reception. If the average level is too high or two low, this is a likely indication that there is a rate mismatch between the far end and local sampling rate. Adjustments are then made to the local sampling rate to adjust for such a mismatch.

Patent CA-2304634-A1 (CA)
Inventor: BRACELAND JOSEPH M
IPC: G07C9/00
Filed: 1998-09-25
Abstract: A distributed biometric identification system incorporates stand-alone workstations. The system generally includes a plurality of stand-alone workstations capable of communicating with a central server remotely located from the workstations. The workstations receive input biometric data, such as fingerprint and photographic data, and compares that data to biometric data stored in the workstation. The workstation compares the input biometric data with stored biometric data to determine whether any of the stored biometric data matches the input biometric data. The results of the comparison are provided to the workstation screen. Workstation mobility is improved by housing the workstation in a self-contained, compartmentalized carrying case.      Workstation mobility may be even further enhanced by housing the workstation in a so-called lunchbox configuration having a main body, a front panel hinged to the main body, and a back panel hinged to the main body. The front and back panels each have a stowed position adjacent the main body, and a deployed position away from the main body. When the panels are in their stowed positions, the workstation (i.e., main body, front panel, and back panel) is a compact, portable unit.

Title: Flight & navigation control unit
Inventor: KAUMARCE PANAHI
IPC: B64D45/00
Filed: 2000-04-19
Abstract: In today's aviation technology, flight information is saved in the Black Box.      When disaster happens, the Box should be retrieved to determine the cause of the crash.      Also in case of fire or accident in dangerous good's sites, refineries, chemical storage's, trains, ship and even armored vehicles, investigators usually are going through the racage and ashes to determine the cause of the disasters.      In this expensive, time consuming and passive way of handling the process information, there is no chance of preventing, early warning or early access to onboard pilots or technicians for any solution or preventive measures. "Real Time Data Transfer Device" or " flight & Navigation Control Unit" will instantly transmits selected data to the base or bases considered for this purpose. Data will be instantly accessible. Analyzing transferred data could be valuable to advise the pilots or operators for safety measures and control.  Instant data will be valuable to prevent future disasters for the same cause.

Filed: 1998-12-29
Abstract: Methods and apparatus for parametrically modeling background noise and generating comfort noise in echo suppression systems are disclosed. According to exemplary embodiments, a background noise model is based on a set of noise model parameters which are in turn based on measurements of actual background noise in an echo suppression system. The exemplary embodiments include autoregressive, autoregressive moving-average and frequency-domain models. An exemplary first-order autoregressive moving-average model includes a single fixed zero and a single variable pole. The single zero and the single pole are sufficient to provide appropriate spectral tilt in the resulting modeled noise, and the single zero ensures that the model is unconditionally stable.  Integration of the exemplary parametric noise models with various echo suppression devices is also disclosed.
Patent CA-2318886-A1 (CA)
Title: Optical amplifier with wide flat gain dynamic range
Inventor: YADLOWSKY MICHAEL J
IPC: H01S3/06
Filed: 1999-02-09
Abstract: An optical amplifier comprises an optical fiber segment (20) doped with impurity ions such as erbium for providing optical gain for an optical signal propagating in the optical fiber segment. A first source (50) of a first pumping wavelength pumps the ions from a first ground state to a second metastable state. The metastable state decays to the ground state by stimulated emission to provide the optical gain. A second source (60) of a second pumping wavelength pumps the ions from the ground state to a third auxiliary state. The auxiliary state decays to the metastable state. Thus, by controlling the pumping power in one or both pumping wavelengths, it is possible to control the fraction of ions in the metastable state. This in turn permits control of an overall scale factor of the gain spectrum without substantially affecting the shape of the gain spectrum.
